SEL Schweitzer Engineering Laboratories

The SEL-3622 Security Gateway by Schweitzer Engineering Labs (SEL) is a robust cybersecurity device that 
combines the functionality of a router, VPN endpoint, and firewall to secure control system communications. It 
supports user-based authentication and authorization for serial and Ethernet-based IEDs, ensuring a strong audit trail. 
With a stateful deny-by-default firewall, advanced cryptographic protocols, and detailed logging, it protects critical 
infrastructure against cyber threats. The device enhances password security, supports multifactor authentication like 
RSA SecurID, and offers cutting-edge IPsec encryption profiles. Integrated exe-GUARD technology safeguards 
against malware, while embedded sensors detect physical and network tampering. Compatible with SEL’s Virtual 
Connect software and NERC CIP compliant, the SEL-3622 is a reliable choice for modern and legacy systems alike.
